I am in the process of spinning up a board with a KSZ8794 chip on it. It’s basically a 4 port ethernet switch where one port is the RMII interface and the other three are normal ethernet connections. This is useful to integrate a small switch on my PCB
This chip allows for communication over both MDIO and SPI. The choice is for the end user.
Since I would like to send a board over to GHI (so they can make it work in TinyCLR ), I would like to know if I am best off connecting the MDC and MDIO pins or should I hook it up to a available SPI on the SC20100S?
